F actin bundles in Drosophila bristles. I. Two filament cross-links are involved in bundling.

The Journal of cell biology - 1 Aug 1995

Tilney L G, Tilney M S, Guild G M

Abstract excerpt

Transverse sections though Drosophila bristles reveal 7-11 nearly round, plasma membrane-associated bundles of actin filaments. These filaments are hexagonally packed and in a longitudinal section they show a 12-nm periodicity in both the 1.1 and 1.0 views. From earlier studies this periodicity is attributable to cross-links and indicates that the filaments are maximally cross-linked, singed mutants also have...
